OK, this is probably a silly question, but why are diopters extra? It would seem to me that it wouldn't be too hard to thread either one or the other EP holders on a pair of BV's to accept a helical focuser.
Instead you have to pay extra for (not just one) two diopter adjusters. The only BV's I've seen on the market with built in helical focusers are the Binomates and BO's new Binoviewer.
Not sure what the percentages are, but I do know that many people wear glasses. And even regular binoculars have at least one EP (usually the left) that has separate focussing adjustments. So why not BV's?
